| 摘 要： | 对台州市8个代表性建筑工地建筑用砂中Cl离子含量进行分析发现,2个建筑工地中Cl离子含量超标,最大超标倍数达1.5倍。对原始海砂中氯离子进行清洗去除发现,原始海砂须经4次清洗,其Cl离子含量才能符合国家相关标准。海砂清洗过程中产生清洗废水,其中一次清洗废水中重金属污染物有超标现象。

| Abstract: | The Cl- content in the building sand of 8 representative construction sites in Taizhou was analyzed in the paper. It has been found that Cl-content of building sand in 2 construction sites exceeded the standard,with the highest over 1.5 times. Besides, the original sand was washed to remove Cl-. It has also been found that the Cl-concentration could reach the relevant national standards after original sand was cleaned 4 times.During the process of washing, waste water is produced. The content of heavy metal pollutants in the first washing waste water exceeded the national standard. |
